Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76720, here are decompositions:

3 + 76717 = 76720
23 + 76697 = 76720
41 + 76679 = 76720
47 + 76673 = 76720
53 + 76667 = 76720
71 + 76649 = 76720
89 + 76631 = 76720
113 + 76607 = 76720

Showing the first eight; more decompositions exist.
